Yes they did hold 2 busses alongside each other. I had pictures of that when we were there watching them do that as a promotional thing years ago.
It would also easily hold 12 cars in the bucket. 4 in each level, stacked 3 levels high.
They always had at least 3 buckets ready for it when it was in use. They kept spare buckets which were always being repaired, for stand-by if one was broken.
They kept 1 bucket from it when they finally scrapped it, and placed it in a memorial park about 12 miles south of where it was last working as a centerpiece of the park. It is on display to the public.
The Miner's Memorial Park-Jesse Owens Park is located on Ohio route 78 and 284/83. Route 284 is named 'Big Muskie Drive.
All of the former mining land has been reclaimed very nicely now. You could never tell it was mined. The 'Wilds' animal preserve is now located in the area that was mined by Big Muskie. It is in a very Rural area, which is now a great motorcycle riding destination area.
If there are any people on this forum that were from that area of Ohio, they may also remember a lot of the big Shovels- 'Super-Strippers' that were out in that part of the state, up around Cadiz area. shovels named The G.E.M., Silver Spade, Tiger, Coal Chief and many more. I remember seeing all of them back in their prime and watching them work.
Most of the coal they mined went to the different Power Companies that generated electricity. Big Muskie was owned by American Electric Power, so our electric bill was very inexpensive back then. Muskie did consume enough electricity to power Las Vegas when working full bore. Muskie was used to fuel the power generating station at Beverly and used to fuel the old station at Philo.
It was told that the shovel held 220 yards-----or 2 greyhound busses in the bucket.
